Update from my end:
I found the old thread where I posted a possible resolution for a similar issue
on CentOS 7.6 with the same protocol (2012):

Some of my initial steps were probably unnecessary, but through a combination
of configuration tweaks and udev rules, the drops seemed to go away.
Of course, if the USB port is not responding at all, that is a separate issue
(is there another computer/cable to verify that with?). You should contact tech
support if that ends up being the case:

(I'm no longer on the tech support team so I couldn't help directly with an RMA
if needed)
Thank you,

I plugged the USB into another host and nothing. Not in lsusb output. No
hotplug messages in the ring buffer.
So is this a busted unit? Is there anyway to reset the USB on the UPC
without power cycling everything attached to it?
